|Boot with a Kaspersky Rescue Disk. This is Linux based disk which will load into RAM only; then it will go online to update itself. Having done that it will then scan the hard drive fully. Likely it will find a few pests/irritants - and deal with them. There are more than a few pests that can/will hide within Widows system files when it's booted yup and are well nigh impossible to remove whilst windows is booted. Hence the Kaspersky Rescue Disk approach (there are other similar disks too from other recognised anti-virus sources). The Linux based disk will not install to the hard drive - unless you tell it to - which don't. The hard drive will merely be a resource the OS installed in RAM only.|
And this a more complete guide to using it:
It's free. Download the ISO; burn to a DVD; boot with the DVD.
Others to run (within windows) - after running Kasperksy"
Junkware Removal Tool (JRT)
JRT installs tl the desktop - from where you run it It will open into a dos style window; follow the instructions therein. It will reboot the system as part of its process.
The above are all free; regularly recommended here; and safe to use.
When you install any of the above... use the manual/custom option - NOT the automatic. Carefully note and uncheck any pre-checked boxes - so helpfully already pre-checked for "your" convenience... By using manual/custom option, and doing as above, you will avoid installing all manner of unwanted "stuff" you really don't want, nor need. Much of it is real PAI to eradicate; can cause all manner of changes and unwanted effect...
Also perhaps install and run unchecky - which does most of the "unchecking" for you; but wise still to double "check".
Retain any logs generated by the above utils; possibly they may be of use if any of the pests persist
